Thinking of this, Yang Yi was shocked, if this is a two-dimensional world, isn't he falling into one dimension? This can't be, this is absolutely impossible!

Falling into a two-dimensional universe? It's a joke!

Although the two-dimensional plane is not new to Yang Yi, even the four-dimensional space node has been encountered by Yang Yi. But to say that he is in a flat two-dimensional space, Yang Yi will never believe it, even in a dream!

Because Yang Yi's knowledge structure does not have theories and concepts that fall into two-dimensional space, he has never thought about such a thing.

But soon Yang Yi smiled bitterly, the scenery of this Phantom Moon City here was so weird, it seemed to be a bit like the three-dimensional universe world he was familiar with, but it was very different from the four-dimensional universe space he had been to in his memory.

It is very much in line with the characteristics of the two-dimensional plane, and the distance can be felt, but the height is not felt. Although the perception of time is changing, the feeling of space is very strange, strictly speaking, the space here is completely incomplete, there is no space in the full sense.

It's a dream, I must be dreaming!

Yang Yi couldn't help shaking his head, and even bit his tongue hard, trying to sober himself up and return to reality. But no matter how Yang Yi struggled, he just didn't wake up.

The scene remains the same, and the city remains the same.

Yang Yi walked towards the city a little helplessly, and found that his body was able to walk freely through the buildings, without any obstruction at all.

These buildings didn't seem to exist at all, and Yang Yi casually pushed on a wall that looked thick, and found that his arm actually passed through the wall, as if there was nothing, without any sense of substance.

Could it be that this is an illusory world, without any real matter? Thinking of this, Yang Yi simply drilled the whole person in, and as expected, the whole person came out from the other end of the wall, and it was really illusory. Everything you see is an illusion and doesn't exist.

Yang Yi still didn't give up, decided to verify his idea again, and ran in the city. The strange thing is that no matter what you hit head-on, it was directly passed by Yang Yi, even if it was a rolling flow of people.

As Yang Yi ran faster, Yang Yi began to pant as he crossed the street, and his physical strength gradually ran out.

After running more than a dozen streets, Yang Yi found that something was not right, if this place was completely illusory, he would definitely not have this kind of physical exhaustion, completely the same feeling as three-dimensional space.

Now Yang Yi is a little broken, this place seems to be virtual but not real, it seems to be real but not real, what is the place?

"Three-dimensional space life, welcome to the two-dimensional cosmic space, a world of energy and color."

When Yang Yi was hesitating, a familiar voice echoed in the depths of Yang Yi's brain.

"Two-dimensional space, what's going on?"

Hearing this voice, Yang Yi was a little surprised in his heart, thinking to himself what the hell this high-dimensional mysterious life form was doing, and asked rhetorically.

"There is nothing strange about it, three dimensions is an extension of two dimensions, and two dimensions is a projection of three dimensions, or the wreckage of the Big Bang.

It can be understood in terms of your three-dimensional cosmic space Big Bang theory, which is that the universe is created by a point explosion with only energy and mass, no time, and no space.

When the explosion began, the primordial energy propelled the formation of time, space, the creation of elements, matter, galaxies, planets, and even the birth of life and civilization.

In the process of expansion and expansion of the universe, energy is propelled. From a point with a high concentration of energy and mass in one dimension, a two-dimensional and three-dimensional cosmic space is created.

But in creating real matter and space, the universe is separated from the two-dimensional and extends infinitely in the three-dimensional space.

Since real matter no longer exists in the two-dimensional space, the two-dimensional becomes the remnant of images and energy left by the expansion of the universe to the three-dimensional space.

Moreover, when the three-dimensional universe expands and expands, the two-dimensional universe also expands synchronously, until the moment the three-dimensional universe stops expanding. ”

Yang Yi's voice in the high-latitude cosmic life form in his brain explained.

"According to you, there really is a two-dimensional space?"

Yang Yi still asked puzzled.

"The two-dimensional universe not only exists, but will continue to be. Unless the energy of the three-dimensional universe expansion is exhausted and cannot support the continued expansion, the gravitational pull takes effect, and the expansion starting point shrinks, the two-dimensional universe will be destroyed in the universe collapse until it is completely compressed into one space, returning to the starting point of the explosion, but this is unlikely to happen. ”

The mysterious high-latitude creature in his brain said calmly.

"Are you saying that the expanding space of the Three Universes will collapse back to its origin? It's unlikely, right? ”

Yang Yi subconsciously asked.

Although Yang Yi knows the Big Bang theory, many cosmologists have made various models of the final outcome of the universe, including the Great Collapse Theory; and the theory of the Great Cooling of the Universe, which pushes energy exhaustion and disappearance after the expansion of the universe to its limit, and expands without collapsing.

Except for the Big Bang theory, the other two theories have not been verified by observations and experiments, and they are still hypotheses that are like a dream in the sky.

"This is just one of many possibilities, and it is unknown whether this phenomenon will occur in the three-dimensional space you are in."

The voice of the high-dimensional life form in Yang Yi's brain came.

"How did I get here? Is it because of you? ”

Yang Yi finally asked the question he was most concerned about.

"The reason why you came here is related to the fusion of your body and my life energy, in fact, your body did not fall into the two-dimensional space, but only fell into the image left by your own three-dimensional space, which is somewhat similar to the so-called dream realm of your human beings."

Cushman & Wakefield's voice said.

"Since it's just an illusory dream, will I be able to wake up?"

Yang Yi said with some concern.

"Hmph, don't think about it when you wake up, you have surrendered your body now, and you will stay in this illusory two-dimensional world forever, in your dreams forever."

The voice in Yang Yi's brain sneered, and suddenly became extremely cold.

Yang Yi felt a pang in his heart, knowing that something was wrong. This mysterious high-dimensional life form actually wants to let itself stay in this illusory world forever, not that he will never wake up, what is the difference between this and death.

"Who the hell are you? Why? ”

Yang Yi asked angrily.

"Hmph, you're just a three-dimensional cosmic lifeform, and you deserve to know my true origin? Do you think that I will help you save the earth and defeat the Maltese at no cost?

I've helped you so much, and I won't be allowed to borrow your body? I can deign to merge the vibrations with you, it's cheap enough for you, and you should be thankful that you're being reused. ”

"You're dreaming!"

Yang Yi shouted angrily. I thought that I really didn't have a good heart, it seems that there is no free lunch in the world, I have been cautious, and I was finally yin by this kind of guy.

From the beginning of entering the so-called four-dimensional space in space, Yang Yi felt that there was something strange in it, but he couldn't find anything wrong, and now the demon he had been worried about had finally come true, and this high-dimensional life form obviously wanted his own life
